FRANCISCO T. DA SILVA TELLES, OF SANTOS, BRAZIL.

BUILDING CONSTRUCTION.

Application filed July 18, 1922. Serial No. 575,904.

To all whom it may (once r ns Be it known that I, FnANoIsoo T. DA SIL'VA TnLLns, a citizen of Brazil, residing at Santos, Brazil, have invented certain new and usefulImprovements in Building Construction, of which the following is a specification.

This invention relates to building con struction and more particularly to a novel and improved wall partition or similar structure adapted to be built up with a smooth, even surface and without the aid f cement or mortar.

The primary object of my invention is the provision of a building construction with particular reference to the wall thereof uhicl i consists of interlocking, superimposed slabs which may be built up without the aid of cement or mortar and which may be assembled with rapidity and speed and without the necessity of skilled labor. a

I accomplish the above objects and others which will become apparent aS the description proceeds and the nature of the invention understood. when taken in connection with the accompanying drawing, wherein,

Figure 1 is a view partly in section showing the wall construction.

Figure 2 is an enlarged detailed sectional view of the complementary and adjoining slabs.

Figuretl is a front view of the wall showing a window frame.

Figure 4 is a rear View of one of the slabs, and,

Figure 5 is a detailed view of the grooved window construction.

Referring now to the drawings wherein like reference characters designate corresponding parts throughout the several views, 5 designates a vertical, corner studding or column preferably provided with vertical grooves along the sides thereof in which the outer and inner spaced slabs 6, 7, are adapted to be positioned during the building construction. Upon the inner face 8 of each slab and adjacent the ends thereof, I have provided ribs 9, 10, the upper and lower ends of said ribs being cut away in a regular curve as at 11, 12, so as to provide the interlocking projections 13, 14, for the complementary top and bottom slabs hereinafter to be referred to. It will be noted that the said projections 13, 14-, of each slab extend somewhat above the top and below the bottom edge of each slab so as to interiit with the projections 15, 16, of the opposite and interlocking slab.

Reference being had in particular to Fig ure 1 of the drawing, the ribs 17, 18 are shown with the projections 17, 18*, extending inwardly from the front wall, or in other words, inwardly of the slab which has been shown broken away. On the other hand, the projections 19, 20, of the ribs on the rear side of the inner slabs extend in the opposite direction so that the superimposed slab when set thereon will form an interlocking connection or joint and thus rigidly maintain an even surface without the aid or use of cement or mortar. Of course if it is so desired, the grooved faces of the top and bottom ribs may have applied thereto any suitable composition to prevent the pos sible displacement of the respective slabs incident to change in atmospheric conditions and it will also be readily recognized that the spaces between the respective ribs may be filled with asbestos or any other filling compound to make the same fire-proof or if so desired, the hollow space between the inner and outer slabs may remain as such.

Reference being had to Figures 3 and 5 of the drawings it will be seen that the win dow frame may be provided with an upper and lower sill 21, 22, and connecting member 23 having an interlocking tongue and groove connection as at 2 1. Vertical grooves 25 in the sides and top of the upper and lower sill are also provided to receive the ends of the respective slabs so that the wall may be around the sill as is well understood.

While I have illustrated and described my invention with some degree of particularity, I realize that in pr ctice various alterations therein may be made. I therefore reserve the right and privilege of changing the form of the details of construction 01' otherwise altering the arrangement of the correlated parts without departing from the spirit of the invention or the scope of the appended claim.

Having thus described my invention, What I claim as new and desire to secure by United States Letters Patent is As a new article of manufacture, a build- 5 ing slab comprising a flat body substantially rectangular in configuration, similarly formed ribs extending inwardly from the inner face of the body adjacent the end edges thereof, said ribs extending above and below the top and bottom edges of the body, 1 the extreme upper and lower ends of the ribs being partially cut away to provide reversely formed projections.

Iii-testimony whereof I afliX my signature.
